Bug: Tree grid collapses on data reload

[ghplink]

Expansion done by user is destroyed when setting new data.

[torsten-sauer]

If you set new data, the information about the nodes that were expanded is destroyed (because you override it).

You have two options:

• track yourself the open nodes and set the information after setting the new data
• update the existing data instead of replacing it completly

ghplink, were you able to find a fix or workaround for this? I'm having the same problem.

Sorry, can't remember and do not have access to source code anymore.
